William Helland-Hansens ekspertise er knyttet til avsetninger og avsetningsbergarter (sedimentologi), spesielt klastiske avsetninger, f.eks. grus, sand og leire og de tilsvarende bergartene, konglomerat, sandstein, og leirskifer. Hvordan transporteres partiklene, hvordan avsettes de, hvordan bygger de opp lagrekker gjennom lange tidsrom og hvilke faktorer kontrollerer bergartenes oppbygning og geometri? Hvordan kan denne kunnskapen anvendes for fjern geologisk fortid, for nær fortid, for samtiden, og for fremtiden?   

William Helland-Hansen ble ansatt ved Universitet i Bergen (UiB) i 1997 etter 12 år i oljeindustrien (Norsk Hydro, 1985-1997). Fra 1998 har han vært professor ved UiB og fra 2007 professor II ved Universitetssenteret på Svalbard (UNIS). Hans faglige interesser omfatter et vidt spekter innenfor klastisk sedimentologi. Forskningstemaer er sekvensstratigrafi, trajektorie-analyse, klinoform-dynamikk, "source-to-sink", grunmarin sedimentasjon, tid- og rom struktur av bassenginnfylling og kystendringer i det 21 århundret. Forskningen er bygget delvis på data  fra norsk sokkel og Svalbard, men også teoretiske analyser fra kontorpulten. Han har deltatt i mange prosjekter, delvis som prosjektleder og han har vært hovedveilder for mer enn 50 master studenter og 10 PhD kandidater. 

I tillegg til forskningen har han et sterkt engasjement for populærvitenskapelig formidling. Han var involvert i oppbygningen av vitensenteret VILVITE, de nye utstillingene på Naturhistorisk Museum, UiB, var hovedredaktør for bestselgeren Naturhistorisk Vegbok, Hordaland, og redaktør og prosjektleder for nettstedet grind.no. https://www.grind.no/
